In the present study, the Brief Behavioral Activation Treatment for Depression (BATD) (Lejuez, Hopko & Hopko, 2001; 2003) was implemented to evaluate its effect on unipolar depression in eight adults. The preliminary results indicate that BATD was successful as there were statistically and clinically significant reductions in self-reported symptoms of depression and in general level of dysfunction. Furthermore, an improvement was found among the participants in overall quality of life. These initial positive results make future evaluations of the intervention interesting. Finally, the limits of the study and suggestions for further research directions are discussed.
